Question

动态地我想使用Jquery生成最近六个月 Demo here

var str = "";
var monthNames = [ "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ];

        for ( var i = 5; i >= 0; i--) {

            var now = new Date();
            var date = new Date(now.setMonth(now.getMonth() - i));
            var datex = ("0" + date.getDate()).slice(-2) + "-" + ("0" + (date.getMonth() + 1)).slice(-2) + "-" + date.getFullYear();

            str += "Date :"+datex+" | Month : " + monthNames[date.getMonth()] + "-" + date.getFullYear()+"\n";
        }

上述代码在一个月的当前日期小于30日时工作正常，如果当前日期为31则上述代码生成具有不相关日期的重复月份。

任何帮助将不胜感激。谢谢。

这是从当月开始的6个月内的最后一次粘贴

var str = "<option value=''>---Select Month---</option>";

        var monthNames = [ "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ];


        var varDate = new Date();
        var month = varDate.getMonth()+1;
        var currentDay = varDate.getDate();


        for ( var i = 5; i >= 0; i--) {

            var now = new Date();
            now.setDate(1);
            var date = new Date(now.setMonth(now.getMonth() - i));
            var datex = ("0" + date.getDate()).slice(-2) + "-" + ("0" + (date.getMonth() + 1)).slice(-2) + "-" + date.getFullYear();

            str += "<option value='"+datex+"'>" + monthNames[date.getMonth()] + "-" + date.getFullYear() + "</option>";
        }

        $(".monthlyErrorReports").html(str);

这是针对当前和上个月的天数/日期

var fullMonthNames = [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ];  

var dateObject = new Date();
var currentMonth = dateObject.getMonth();
var strDateList = "<option value=''></option>"+"<optgroup label='--"+fullMonthNames[currentMonth]+"--'>";
var noOfDatesInMonth = daysInMonth(currentMonth,dateObject.getFullYear());
var varNoOfDaysFlag = noOfDatesInMonth;
var varItterationBreakFlag = true;
var varNoOfItteCount = 0;
var varTotalDaysCount = noOfDatesInMonth;
var currentDate = ("0" + dateObject.getDate()).slice(-2) + "-" + ("0" + (currentMonth+1)).slice(-2) + "-" + dateObject.getFullYear();
var previousDay =  new Date(new Date().setDate(new Date().getDate() - 1));
    previousDay = ("0" + previousDay.getDate()).slice(-2) + "-" + ("0" + (previousDay.getMonth()+1)).slice(-2) + "-" + previousDay.getFullYear();

for(var i = 1; i <= noOfDatesInMonth ; i++){

    var dropdownValue = ("0" + i).slice(-2) + "-" + ("0" + (currentMonth+1)).slice(-2) + "-" + dateObject.getFullYear();

    strDateList += "<option value='"+dropdownValue+"'>" +("0" + i).slice(-2)+"-"+ monthNames[currentMonth] + "-" + dateObject.getFullYear() + "</option>";

    ++varNoOfItteCount;

    if(varNoOfDaysFlag == i && varItterationBreakFlag){

        dateObject = new Date(dateObject.setMonth(dateObject.getMonth() - 1));
        currentMonth = (dateObject.getMonth());
        noOfDatesInMonth = daysInMonth(currentMonth,dateObject.getFullYear());
        i = 0;
        varItterationBreakFlag = false;
        varTotalDaysCount += noOfDatesInMonth;
        strDateList += "</optgroup><optgroup label='--"+fullMonthNames[currentMonth]+"--'>";
    }

    if(varTotalDaysCount == varNoOfItteCount){
        noOfDatesInMonth = 0;
    }
}           

strDateList += "</optgroup>";   

$(".NoOfDateList").html(strDateList);
